Using Bus Connectors

It is possible to make multiple connections between subcircuits and
elsewhere within a schematic, using bus terminals and connectors.
These act like ribbon cable, making multiple connections through
single graphical objects. This can greatly simplify the schematic
visually.

Bus terminals are terminal devices that provide multiple contacts.
Bus subcircuit connectors (BSCs) are locations of a subcircuit where
multiple connections can be established. Bus terminals can be placed
on BSCs, or can be connected to other bus terminals, and BSCs can
connect together directly. Bus wires can also be used to connect bus
terminals and BSCs.
